Work tables, in particular office tables and office table systems, are known in many forms. Sit-stand systems are increasingly finding their way into modern offices. This also applies to "Smart Office" technology and the Internet of Things ("Internet of Things").

In connection with electrically height-adjustable tables in particular, there is a need for predictive remote maintenance, preferably in combination with an initial simple fault diagnosis and remedy. In addition, the recording of room or table occupancy is of interest for data-based office and building planning.

In addition, so-called "coworking spaces" are becoming increasingly interesting, especially for start-ups, small business owners and freelancers. Coworking spaces are both offices and exchanges. Coworking spaces are also an advantage in open-plan offices, for example, because they allow flexibility for occasional and / or alternating work in, for example, changing project groups. In this context, but also in connection with other work concepts, a simple remote booking of workplaces or tables would also be an advantage.

In the case of electrically height-adjustable tables, when a position changes from sitting position to standing position and vice versa, the table height (table top height) must be manually adjusted by a user by actuating an operating element.

The furniture system 1000 shown in FIG. 1 comprises an electrically height-adjustable table 1 with two electrically height-adjustable table legs 12, an electric motor 121 per table leg 12 for height adjustment of the table top 11, a motor control device 13 for controlling the two electric motors 121, and a sensor device coupled to the motor control device 13 17 (see Figures 2 and 3) for the temporal acquisition of a value of at least one motor characteristic number per electric motor 121. The motor control 13 also serves to store the acquired values of the at least one motor characteristic number.

Furthermore, the furniture system 1000 comprises a communication module 14 with a control and evaluation device for evaluating the values of the at least one engine identification number detected by means of the sensor device 17 with regard to a deviation from a respective engine identification number reference value, which can be via a data connection, which can be wired or wireless the motor control device 13 is coupled.

Furthermore, the furniture system 1000 comprises a remote computer, in particular a server, with a web interface and a browser interface, which is connected to the communication module 14 via a data network 16, in this example the Internet. In FIG. 1, only one data storage device 4 is visible from the remote computer. The computer also has means for advanced remote fault diagnosis in the electrically height-adjustable table 1. Of course, a large number of electrically height-adjustable tables can also be connected to the remote computer.

The fault diagnosis can take place, for example, via the motor current consumption of the electric motor (s). For example, an average and a standard deviation can be formed and compared with "standard values". Depending on the size of the deviation, a chronological profile of the motor current consumption is called up in order to be able to carry out a more precise analysis and diagnosis.

For example, pulses from Hall sensors can determine the rotational speed of the electric motor or electric motors in order to calculate the driving speed of the table top. In this way, the stability / regularity of the process of the table can be assessed and certain “defects” can be identified locally via the temporal motor current consumption.

Alternative non-destructive test methods, such as X-ray images for visual binding diagnosis, require a certain amount of material, personnel, security and Time expenditure.

The control and evaluation device is set up to retrieve the time profile of the detected values from the engine control device 13, to save it and, if the determined deviation exceeds a predeterminable limit value, to check for errors, to categorize any error found and to store the error category locally and, if necessary, to forward it to the local display and to send an error diagnosis report together with the time course of the recorded values of the at least one engine identification number to the data storage device 4 in the remote computer for storage and for carrying out an extended remote error diagnosis. The fault diagnosis report can additionally or alternatively also be sent to a subscriber of the data network 16, who in the present example is a computer 5 and has a display device 6. As can be seen from the right-hand side of FIG. 1, the communication module 14 is set up to check the availability of firmware updates for the engine control device 13 and / or for connected peripheral devices and firmware updates to the engine control device 13 and / or wirelessly to the peripheral devices transferred to.

For this purpose, for example, the subscriber or a subscriber of the data network 16 can additionally or alternatively be used.

The communication module 14 is also set up to cause usage and height adjustment data from the table 1 and / or utilization data of the table 1 to be stored in the data storage device 4 of the remote computer.

The communication module 14 advantageously has at least one radio interface, e.g. WLAN, Bluetooth, Zigbee or NFC interfaces for communication with peripheral devices and for communication via the data network 16 with a subscriber of the data network.

In FIG. 2, a table leg 12 of the table from FIG. 1 as well as the electric motor (gear motor) 121 and a spindle drive (122) are shown by way of example and schematically. In connection with the sensor device 17, the time Currents of current and speed (of the height adjustment) with in this case constant voltage at the beginning of the movement of the table top recognize normal operation (FIG. 2 right) and also an operation deviating from normal operation (FIG. 3 right). This is shown schematically on the right in FIG. 3 for the case of spindle wear 127. If such an anomaly 128 is detected, the communication module 14 can, for example, issue a corresponding warning and / or a maintenance notice via a suitable display device. Alternatively or additionally, for example, the height adjustment function can be blocked for safety reasons.

During the measurement phase, identified in FIG. 2 and in FIG. B. current, voltage and speed curves measured as a function of time and stored. For example, the mean values of the respective courses at the end of a journey are stored in the control and evaluation device and forwarded to the data storage device 4 via the communication module 14. At the same time, a comparison is made of the respective temporal profiles during the measurement phase with a predefinable limit value. In the event of an overshoot (FIG. 3), the time profiles at the end of the journey concerned are stored in the control and evaluation device and forwarded to the data storage device 4 via the communication module 14. The temporal analysis of the current profile offers, for example, the possibility of a mechanical resistance, e.g. B. spindle wear 127, in the spindle drive 122 to locate and fix. In the future, archiving and categorizing errors will make it possible to identify the cause of the error more quickly (e.g. incorrect operation, transport damage, production defect, material quality, etc.).

FIG. 4 shows a flowchart of a method for carrying out a local fault diagnosis and, if appropriate, an extended remote fault diagnosis according to a special embodiment of the present invention. After receiving a move command (S121), the motor control device 13 issues a command to move the table in the corresponding direction (S122). After the end of the method, motor data acquired by means of sensor devices, such as, for. B. motor current and Hall sensor pulses, stored in the control and evaluation device, averaged and evaluated (S123). If the motor data has a limit exceed, the control and evaluation device reports an anomaly (S124), which triggers a local check of the time recording of the motor data (S125) and sends a fault diagnosis report with a detailed history of the motor data and categorization of the fault to the central data storage device 4 (S126). The user of the table is then informed of the category of the anomaly and of a corresponding measure for correcting the anomaly or the error on the table display (153) (S127). Finally, the engine data are saved in the log file of the engine control unit.

FIG. 5 shows details of an example of an operating device 15. This can be a so-called hand switch. In this example, the operating device 15 has an operating element 151 for raising and an operating element 152 for lowering the table top. A high-resolution display 153 can also be provided.

Furthermore, the operating device can have the communication module 14 or parts thereof, wherein it is identified here with the reference number 154, and an NFC reader 155.

The display 153 can, for example, display the booking information of the workplace and / or the table height, an indication of a physical activity, such as e.g. Get up, and / or serve a status and / or error message of the workplace.

The NFC reader 155 can serve to provide an authorization means such as e.g. to read a chip card (not shown) of a user and to check whether the user is authorized to use table 1 or workstation, for example due to a remote registration or booking. The remote booking can be made, for example, via a participant in the data network 16 with the remote computer.

FIG. 6 shows a flow diagram of a method for data-based assignment of workplaces (see FIG. 7). The initial situation of room A (S131) is compared with data on the room occupancy of the respective workplaces APi (ARi, AP2, AP3 and AP4) (S132). Figure 7 shows the respective room data per employee Mj (Mi, M2 and M3). The use of a workstation APi by an employee Mj is defined as a variable DTij (see FIG. 7). An employee Mj is assigned to a specific workplace APi if the utilization DTij> DTi is exceeded (reference value for minimum use of a workplace). FIG. 7 shows an allocation of four workplaces by evaluating the utilization over three employees with an exemplary limit value DTi = 50%. Figure 8 shows a filtering of sensor data over a table group of four workplaces. In this example, categorization is based on the level of the measured sound pressure level at the workplace in dB. In this case, work station AP4 is marked as 'too loud'. After successfully assigning a job to an employee (shown in FIG. 7), FIG. 9 shows attributes of a use of the table (current table height) by the employee and presence information of the employee (location where the employee is located and availability for a conversation).

In FIG. 10, two electrically height-adjustable table legs 12 and a motor control device 13 with communication module 14 are shown as examples. A computer 5 with display device 6 can information such. B. table height or motor data, and commands such. B. up or down, with the engine control device 13 via a data interface such. B. exchange a USB or other so-called human interface device (HID) cable. Via a pre-installed operating software 61 in the computer 5, the user can use a height-adjustable furniture system, such as. B. the furniture system 1000 of FIG. 1 interact better and easier. First, the user must first register in the system, which can be done, for example, using the operating software (desktop app) 61 (611). Personal parameters, such as B. favorite seat and standing height or weight for calculating calories burned, can be entered there for user profile setting 611. This user data 63 is to the data storage device (z. B. Cloud database) 4 via a wireless protocol, such as. B. http, transmitted. The availability of this user data 63 in a cloud database 4 ensures that personal user parameters are reproduced independently of desktop computers or connected height-adjustable tables. Such data is reproduced after login 612 by the same desktop app 61 via login and password. Optionally, the user can decide to remain logged on to the computer 5 with the operating software 61, which is a direct user identification after a Computer startup allowed. After a user has successfully logged on, the height-adjustable table can be operated via the operating software 61 with personal settings (613).

In FIG. 11 (left), an operating device 15 is connected to the engine control device 13 and identified on the right. The control device 15 serves as an interface for controlling the height-adjustable table, and u. a. for storing favorite table heights. A user login e.g. B. via RFID is possible by the NFC reader 155. After detection via the reader, the ID number is transmitted to the cloud database 4 via a communication module 154 and compared in the user database. After the user has been recognized, user settings such as B. favorite table heights, transferred to the control device and saved.

FIG. 12 shows an example of a method for user login (S611), both via operating software 61 and via an RFID card. Using the desktop app, a user is identified via login and password (S612), which can be entered directly via the desktop app or via a web platform when registering for the first time. In the case of RFID cards, these cards are first distributed to the users by the user of the interface and linked to the user accounts. The entry of login data or the RFID number is forwarded wirelessly to the database and checked there (S613). Non-existent or not allowed users lead to the display "User unknown" or "User not allowed" (S617). In the case of valid users, the user data are retrieved from the database and transmitted to the operating device 15 when registering with RFID or to the operating software 61 when logging in / password. The user is reassigned in the booking system at the work station (S615) and displayed on the display of the operating device 153 (S616).

FIG. 13 shows part of a furniture system 1300. Not shown is an electrically height-adjustable table, which has at least one electrically height-adjustable frame, in particular an electrically height-adjustable table leg, with at least one electric motor, via which height adjustment is possible, a motor control device for controlling the at least one electric motor, and a Radio communication module, which is connected to the engine control device. However, it is an associated chair 3 with a 3-axis acceleration sensor 32 in this example and an associated evaluation unit for evaluating the time profile of the acceleration in the vertical direction (z direction) detected by the acceleration sensor 32, for determining whether a user is 2 has sat on the chair 3 or got up from it, and a radio communication module 30 connected to the evaluation unit for sending a command signal to, for example, the motor control device 13 via the radio communication module of the table, the command signal being used to automatically start up the table top when the evaluation results has that the user 2 has switched from a sitting position to a standing position (see the process indicated in FIG. 13 on the left), and serves to automatically lower the table top when the evaluation has shown that the user 2 has changed from a standing position to a sitting position Ha t (see upward movement of user 2 in FIG. 13 on the right).

As shown in FIG. 14, a change in position can be determined on the basis of the time-dependent acceleration behavior of the chair or the seat surface. The left-hand part of the graphic in FIG. 14 shows the time behavior of the acceleration when sitting down, while the right-hand part of the graphic shows the time behavior of the acceleration when standing up.

FIG. 15 shows an example of a method for automatically adjusting the height of the table top of an electrically height-adjustable table in accordance with a particular embodiment of the present invention using a flow chart. When the chair (e.g. chair 3) is in the rest position (S141) and after receiving an initialization signal (S142, e.g. via the table control (e.g. control device 15)), the acceleration sensor, e.g. B. acceleration sensor 32, calibrated so that the position of the chair and the Z direction is recognized by evaluating gravity in the rest position of the chair (S143). Movement of the chair triggers an impulse e.g. B. from an energy-saving vibration sensor (S144), which is provided for waking up a detection module mounted under the chair (z. B. detection module 300) (S145). The timing of the

Acceleration is evaluated (S146) and reported for the purpose of monitoring one unwanted presence (S147). If a limit value of the acceleration in the Z direction is exceeded, as shown by way of example in FIG. 14, the user's seating position is reported back to the control and stored in a database (S148).
